    摘要： A dielectric antenna includes a plate-shaped dielectric substrate, a radiation electrode provided on a first main surface of the dielectric substrate so as to cover the first main surface except for a peripheral portion thereof, and a ground electrode formed on the entirety of a second main surface of the dielectric substrate. A feed electrode extends through the dielectric substrate from the first main surface to the second main surface. A feed point of the feed electrode is electrically connected to the radiation electrode. A plurality of through-hole electrodes providing an electrical shield are formed in a peripheral portion of the dielectric substrate so as to surround the radiation electrode, the through-hole electrodes being connected to the ground electrode. Alternatively, instead of the through-hole electrodes, the dielectric antenna may include a shield electrode formed on a side surface of the dielectric substrate and connected to the ground electrode.

    摘要： A dielectric filter for a high frequency band includes a plurality of resonators formed by boring a plurality of through holes between the oppositely disposed end surfaces of a dielectric block in parallel with each other and arranging internal conductors on the inner peripheral surfaces of the respective through holes and an external conductor formed on a substantial portion of the outer peripheral surface of the dielectric block. A non-conductive region is formed on the short-circuit end surface and extends in parallel with the direction connecting the resonators, thereby the filter can be controlled satisfactorily for coupling the dielectric coaxial resonators and have a reduced height.

    摘要翻译： 用于高频带的介质滤波器包括多个谐振器，该谐振器通过在介质块的相对设置的端面彼此平行地钻孔多个通孔而形成，并且将内部导体布置在各个通孔的内周面上 以及形成在介质块的外周面的主要部分上的外部导体。 在短路端面上形成非导电区域，并且与连接谐振器的方向平行地延伸，从而可以令人满意地控制滤波器以耦合介质同轴谐振器并具有减小的高度。
